**Perl**is both the name of a programming language and the name of the primary implementation of that language.

As a language, it takes the best from other programming languages such as BASIC, Lisp, C and the Unix tools sed, AWK and the UNIX shell. It is particularly suited for Unix systems programming, text processing and gluing heterogeneous programs together. Its interpreter is called perl. Perl has seen five major revisions, and a sixth is currently being worked on.

The implementation known as Perl is available on a wide variety of mostly UNIX-based operating systems.
